Why and Where are Tilt Sensors Used

 

1. Why do people monitor tilt angles?

The world is constantly changing, and the tendencies of different objects and machines can provide insight into worrying trends and potential future problems. There are many reasons why people need to monitor the Angle or degree of inclination.

Avoid accidents and injuries
One reason is that it can help prevent injuries and avoid accidents. When people work on the slope, they need to pay attention to the Angle of the slope to ensure that they do not slip. If the Angle is too steep, it can cause an avalanche, which is very dangerous.

Ensure the normal operation of the device
Another reason to monitor the tilt Angle, or tilt, is to make sure the equipment is working properly. For example, if a machine is not level, it may not work properly. This can be dangerous for the person using the device and the people around it.

2. Where can the tilt sensor be used?

Tilt sensors can be used in many applications, such as the Marine industry, construction industry, infrastructure monitoring, etc.

Marine industry
Tilt sensors can be used on ships to measure ship roll and pitch. This information can be used to improve the stability of the ship and avoid capsizing.
Construction industry
In many construction machines, such as excavators and bulldozers, tilt sensors can be used to measure the Angle of the machine blade or bucket. This information can be used to automatically adjust the position of the blade or bucket, or to provide feedback to the operator.
Infrastructure monitoring
Tilt sensors can be used to monitor the status of infrastructure such as Bridges and buildings and alert authorities to potential hazards, such as leaning towers. By continuously monitoring the tilt of the structure, the sensors can detect even the smallest changes that could indicate a problem. In the event of a potential accident, sensors can provide critical information that can be used to evacuate people and take other safety measures.
Tree bend monitoring
Some trees may fall after storms, typhoons or other natural disasters. Tilt sensors can be installed at a certain height on these trees to monitor their x, y, and z values in real time. This can provide insights into tree tilt and movement and help make timely, effective decisions to protect trees and people.
Gate monitoring
In car parking lots and parking garages, the normal operation of road gates is crucial to the normal toll collection. The tilt sensor can be installed in the guardrail housing, especially suitable for the guardrail Angle measurement and movement detection, to determine whether the guardrail is dropped, bent or broken, if there is a trigger alarm, so that maintenance personnel can take measures in time. Ensure regular charges.

The optimized internal design of multi-layer structure, sealing ring, and three anti-coating further enhances the waterproof and dustproof capability.

The ER-TS-3160VO voltage uniaxial tilt sensor is an analog voltage uniaxial tilt sensor. The user only needs to collect the sensor voltage value to calculate the tilt Angle of the current object. The built-in (MEMS) solid pendulum measures changes in the static gravity field, converts them into changes in inclination, and outputs them via voltage (0~10V, 0.5~4.5V, 0~5V optional). The product adopts the non-contact measurement principle and can output the current attitude and inclination Angle in real time.

How do MEMS Tilt Sensors Work?

 MEMS tilt sensors, as the name suggests, are tilt sensors manufactured by MEMS (microelectromechanical system) technology, which has the obvious advantage of very accurate measurement.

Here we explain the principle of MEMS tilt sensor through an example.

In simple terms, the MEMS tilt sensor is a non-contact measurement of the inclination of the target object through the Earth's gravity. In essence, the tilt sensor measures acceleration, especially gravitational acceleration, so it has an integrated accelerometer chip. The acceleration sensor chip consists of a MEMS sensing component and a peripheral signal processing circuit. The MEMS sensing components are shown as follows:

The blue part of the MEMS sensing component is mobile, while the red part is fixed. When accelerating or decelerating, the blue part will move left or right, and the capacitance between the blue and red parts will change accordingly. Acceleration can be determined by measuring the capacitors C1 and C2. As shown in the picture below:

That is, the acceleration or deceleration that occurs when the object is tilted causes the movable part of the MEMS sensing component to move to one side, as shown below:

It can be seen from this principle that the MEMS sensing component is very sensitive to vibration during the measurement process, and the vibration of the measured object will affect the measurement result. So filters must be added to eliminate interference beyond a certain frequency. Some MEMS tilt sensor manufacturers will also be equipped with filters according to user needs. There are two types of filters: Butterworth filters and Critically damped filters. Batvots is more suitable for measuring non-moving, high vibration objects, such as large drilling platforms; Critical damping filters are more suitable for measuring moving objects, such as engineering vehicles, agricultural vehicles, etc. The vast majority of tilt sensors on the market today are equipped with Butterwart filters only, or no filters at all.

Ericco’s ER-TS-3160VO built-in (MEMS) solid pendulum measures the change of static gravity field, which is converted into the change of inclination, and the change is output through the voltage (0~10V, 0~5V optional).
